McIntosh announces the MHA200 Vacuum-tube headphone amplifier

News

MHA200 features a compact footprint (just 15.6 cm wide and 23.2 cm deep), 4 selectable headphone impedance ranges, balanced and unbalanced analog inputs, 4-pin XLR and double 3-pin XLR headphone outputs.

A pair of 12AT7 and 12BH7A dual triode vacuum tubes power the compact MHA200. The 12AT7 vacuum tubes amplify the incoming audio signal while the 12BH7A tubes provide the power to drive the output to your headphones with low distortion. The MHA200 uses a pair of our Unity Coupled Circuit output transformers to deliver pristine audio to your ears.

A wide assortment of connectivity options come on the MHA200. For attaching your headphones, there are 3 options: a pair of 3-pin balanced XLR connectors for dedicated Left and Right balanced output; a 4-pin balanced XLR connector for balanced stereo output; and a 14” stereo headphone jack. For connecting the MHA200 to your home music system’s source components, it has 1 set each of both balanced and unbalanced inputs.

The MHA200 takes advantage of unique McIntosh technologies to create the best possible personal listening experience. The Unity Coupled Circuit transformers have been adapted to produce 4 headphone impedance ranges of 32 – 100, 100 – 250, 250 – 600, and 600 – 1,000 Ohms at 500mW so that virtually every headphone can receive legendary McIntosh sound quality and performance.

It features custom output transformers to match the tube amplifier section to the headphone output section in order to ensure maximum power transfer for various headphone loads. Instead of having to adapt to the impedance of the headphones with voltage gain in the input stage, the Unity Coupled Circuit output transformers’ secondary windings ensure the full power of the MHA200 is available regardless of the impedance of your headphones.

McIntosh MHA200 will be priced at $2500 in the USA and £2795 in the UK, European price is TBA.
